Post subject: QNX debugging by TRACE32 - Can't look at all symbols of proc

Dear Everyone.
I'm debugging my BSP by TRACE32.
I built bsp-xxxxx.ifs and procnto-instr.sym.
I loaded bsp-xxxxx.ifs by TRACE32's Data.Load.Binary command at the SDRAM
memory region (0x10800000), which I set up as the System
Build/Property/General/System/Image Address.
At TRACE32,
I performed like the below
Data.LOAD.Binary C:\QNX632\ide4-workspace\bsp-jaguar\Images\bsp-jaguar.ifs
A:0x10800000 //verify
if data.long(&DNLD_ADDR)!=0x00ff7eeb
(
print "Wrong QNX image magic!"
stop
)
Register.Set PC data.long(&DNLD_ADDR+0x0c) ; startuphdr.startup_vaddr
Data.Load.Elf
C:\QNX632\ide4-workspace\bsp-jaguar\Images\startup-jaguar2eval.sym /nocode
Data.Load.Elf C:\QNX632\ide4-workspace\bsp-jaguar\Images\procnto-instr.sym
/nocode /noclear
I go my QNX and stop at any point.
I could check the startup-xxxxx2eval's symbols by TRACE32's symbol.browser.
I could look at Symbols, Variables, Functions, and Modules by
symbol.browser.
However, I could NOT look at the procnto-instr's all symbols.
I could see Global symbols and Global variables(os_version_string and
timestamp), but could NOT see any Global Functions.
How can I obtain the procnto or procnto-instr with whole Function symbols ?
My BSP went to "__hardcrash".
I looked at the below data at the window of TRACE32's Var.Frame.
SR:0xFFFF:0xFC4046D8(asm)
scrn_display(asm)
kprintf(asm)
shutdown(asm)
kdebug_enter(asm)
arm_undef(asm)
__und_entry(asm)
---> exception
SR:0xFFFF:0xFC404174(asm)
This looks like the call stack.
What's the problem ?
Please give a comment.
Additionally, I also set up the parameters below examples.
